Star

For this variant you will need 5 players. Assign each player a color, that player must have a 60-card minimum deck using only cards of their color, and colorless cards.  Players cannot produce mana of colors other than their chosen color.  Each of the players should sit in a circle next to his allied colors.  They are his allies, the non adjacent players are your enemies. The setup should look like the Mana Pentagon on the back of a Magic card (see the image at the left). You allies are not considered opponents for purposes of spells that specify “target opponent”, though you may attack them. The sequence of turns follows a “star” pattern. The white player plays first, and is followed by the black player, then the green player, then blue and finally red.  Players may split thier attacks amongst any number of plauers.  The goal of the game is to defeat your two enemies before anyone else accomplishes the goal. Failing that, you may prevent other people from winning the game, and perhaps be the last player standing.
